Description
The present invention relates to method and device that a kind of elevator system safety arrestment is stopped, a kind of gig master that more specifically says so restrict friction braking method and device.Be applicable to well winch elevator system and elevator lifting system.
The safety catch of existing elevator system is for being installed on the winch drum or being installed on the transmission shaft, perhaps provide opposite electromagnetic force distance by electrical motor, these devices all are installed in the hoist house, handled by unified electric-control system, the time have Control Failure, major accidents such as operation sport car etc. to take place, when between the master of friction winding system hoisting cable and friction wheel, seriously skidding especially, above-mentioned brake mode all can't realize safety arrestment, lifting container hypervelocity driving out of control causes serious abominable accident.
281 pages of " coal mine special equipment design calculation " book of publishing in the Coal Industry Press disclose a kind of BF type falling protector, and the cardinal principle of its arresting agency is to produce the effect of arresting by sliding wedge extruding check band.During normal the lifting, be contained in four small extension springs in the cage upper frame, the effect by main tie, connecting plate, fork arm is stretched; In case disconnected rope is carried steel wire rope tension and is disappeared, the spring that was stretched originally, shrink this moment, drives fork and rotate around its axle, the sliding wedge that is contained in the catching device box provoked the wedging check band.Safety arrestment when this device only is used in the disconnected rope of single wire winding type winch elevator system is worked when having only main hoisting rope to pull apart, and complex structure, can't be used on the main hoisting cable, realizes safety arrestment.
Purpose of the present invention just provides a kind of gig master restrict friction braking method and device, has solved braking problem when main hoisting cable and friction wheel seriously skid.
Purpose of the present invention can realize by following manner: on the collision prevention girders of headframe brake equipment is installed, is made main hoisting cable pass brake equipment, when normally promoting, steel rope can freely pass through brake equipment; When between rope speed is above normal permissible value or friction wheel and steel rope, serious slide relative being arranged, start brake equipment, make to produce great friction drag between brake equipment and steel rope, realize emergency thereby lifting container is slowed down.
Brake equipment of the present invention mainly is made up of rope clamping block and driver train, and two rope clamping blocks are installed in the both sides of steel rope, and driver train is used for handling the rope clamping block action, and when normally promoting, steel rope can freely pass through rope clamping block; When between rope speed is above normal permissible value or friction wheel and steel rope serious slide relative being arranged, driver train starts, and makes two rope clamping block move toward one another, grips steel rope, produces great friction drag, realizes emergency thereby lifting container is slowed down.
The present invention has following advantage compared with prior art: solved the hard nut to crack of elevator system, particularly friction winding system safety arrestment when between friction wheel and steel rope serious slide relative being arranged, the safe reliability of elevator system is improved greatly; Apparatus structure of the present invention in addition is simple, safe and reliable, manufacturing, easy for installation.
